BackRack L

Bontrager BackRack L

Bontrager's BackRack L is made for mountain and hybrid bikes with frame sizes 18 inches and over, and road bike frames 54cm and over. This durable and light rack is perfect for turning your bike into a commuter and errand-runner. Tough and rustproof stainless-steel hardware is included and the single-bolt strut mounts allow for maximum adjustablility and ease of installation. And, the BackRack is compatible with standard trunk bags and panniers as well as Bontrager's Interchange models (sold separately).

Awkward installation, but once finished, it is a solid accessory. It creates a lot areas underneath the rack that are hard to clean with a rag, but my fenders don't let it get too dirty. I also have a Bontrager trunk bag that mounts/dismounts with the Interlock option on this rack, which works perfectly.

This rack is for my 2014 Trek 7.2 FX disc. There is a disc version of this rack but I didn't need it because there were no special fitment issues with my bike. It only took 15 minutes to install and is very sturdy. I'm using an interchange bag. I bought a Bontrager system because it was specifically designed for my bike (as opposed to other brands would be a more generic fit). Pretty much a slam dunk.

I purchased this rack to hold panniers. It's all it will be used for. It's feather light, pretty rigid for aluminum, and has a tab to hang a blinky. I have a weird frame made by SE Bikes. The bike is a Hopworks Pub Runner. It's a single speed that I ride fixed, nothing special. I had to fabricate a support to fit around my brakes and get longer lower mounting screws because I run fenders during the rainy season.
For the models of bikes that require no modifications, install should be very easy and you will have a rigid rack. For the weird frames like mine, you will be better off buying a rack that has the flat steel upper mounting brackets for ease of installation. I have access to a full blown machine shop, so fabricating a custom upper mounting bracket was just a matter of an hour's work and some paint.
Just be wary that the install may not be straight forward. Better yet, for $15 or $20, have the dudes in the shop throw it on for you. They've done hundreds.

Looked all over for a rack that fit my Trek hybrid AND my ancient Cannondale trunk bag.
The wide middle "sort of" acts as a fender.. it doesn't completely block "back spackle" but it reduces it.
It's nice and rugged looking in its matte black finish. It would fit on a road bike.. but I think it'd look a little out of place and I'd recommend it for a hybrid or MTN bike.
